Carpet sweeper



Patented Feb. 16, 1932 3 UNITED STATES PATENT OFFICE IRA J. OWEN, OFGRAND RAPIDS, MICHIGAN, ASSIGNOB TO IBISSELL CARPET SWEEPER COMPANY, OFGRAND RAPIDS, MICHIGAN CARPET SWEEBER Application filed March 19, 1926.Serial No. 95,887.

This invention relates to an improved, cheap and simple construction ofcarpet sweeper adapted to toy size. The structure is available for fullsize carpet sweepers.

The objects of the invention are:

First, to provide improved driving parts and arrangement of the same.

Second, to provide an improved case and assembly support, and reinforceand connection for the bail of the handle.

Third, to provide an improved case and frame construction whereby theseparts are retained in effective operative relation.

Fourth, to provide a structure which is especially well adapted to thesimple fiber case.

Objects pertaining to details and economiesof my invention willdefinitely appear from the detailed description to follow. The inventionis clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings forming a part of thisapplication, in which:

Fig. l is a side elevation vlew of a toy carpet sweeper embodying thefeatures of my invention, a part of the handle being broken away.

Fig. 2 is an enlarged detail end elevation view with the handle insections.

Fig. 3 is an enlarged detail sectional View on line 33 of Figs. 1, 4 and2, the floor and brush wheels being in full lines.

Fig. 4 is an enlarged detail sectional view on line 44 of Figs. 2, 3, 5and 6 showing details of one of the floor wheels and its axle and itsconnection and relation to the dust pan and other parts of thestructure.

Fig. 5 is an enlarged detail sectional view on line 55 of Fig. 1, 3 and4.

Fig. 6 is an enlarged detail sectional elevation view on line 66 ofFigs. 1 and 4.

The parts will be identified by their numerals of reference which arethe same in all the views.

1 is the main body of the case having ends 2 suitably slotted at 21 toaccommodate the brush spindle. 3 is the brush of usual twisted wire axleform retaining the bristles by that means. 4 is the brush wheel having arounded projecting pivot hub 41 at its center to constitute the journal.5 is the guard, brush and wheel support plate, having a bearingdepression 51 at the center for the pivot hub 41 of the brush wheel 4.It is formed of sheet metal and has a flat angular attaching base 52retained in place by nails 53, the angle 54 projecting over the top ofthe case end to form a guard and reinforce at that point. A horizontalportion 55 extends outwardly from the end of the case and thendownwardly in the offset at 56 to form the floor wheel retainer, thesame projecting slightly laterally at 57 and being reinforced at thatpoint by struck up rib portions 57. These retain the floor wheelsagainst longitudinal displacement and permit them to play freely up anddown and laterally into contact with the brush wheel. The plate isperforated at 58 for the bail pivot. The same is a reinforcement for thehandle bail pivot hearing which projects therethrough into the end ofthe case.

The dust pan 6 is carried by pivots 61 which are the axles for the floorwheels. These project outwardly at each 'end through enlarged apertures22 in the case ends 2 as seen in Figs. 3, 4, and 5, the position of thedust pan being indicated by dotted lines at the right of Fig. 5.

The dust pans 6 are rabbeted into a shoulder 62 at their outer edges toengage under the edge of the case. The floor wheels 63 are carried onthe axles 61 and are provided with hubs 63 of suflicient size to coverthe aperture 22 in the side of the case which insures freedom ofmovement.

It will thus be seen that the floor wheels are connected to and carrydirectly the dust pan and serve the additional duty as they are pivotalsupports for the dust pan. Their movement is limited by the aperture 22which is suificiently large to allow the needed play of the parts.

A spring 64, see Fig. 6, is folded on itself at the center and projectsupwardly into contact with the inside of the top of the case midway ofthe ends and at the end. The lower end of the spring is turned at rightangles and terms a pivot at the upper inner corner of the dust panparallel with the axle.

The spring being put under tension serves to force the inner end of thedust pan down and close the outer edge against the case and tensions thefloor wheels in position. lVhen the case is forced down by the actionupon the handle in operating the sweeper, it carries the end bar withthe brush down into yielding contact with the floor wheels which drivesthe brush. The floor wheels serve as the support for the dust pan at thesame time.

lVhen further stress is applied, enough to cause movement, the entirecarpet sweeper case and the brush are forced down against the floor,thus securing the broom action when the carpet sweeper is actuated.

The car )ct sweeper is provided with the usual bail handle 7 which ispivoted in apertures at the ends of the case. The pivot projects throughaperture 58 in the guard plate 5, as before stated, and there is struckup on the guard plate the angular rib 59 to support the sait bail out ofcontact with the guard plat-e so that it will swing freely in use. Thereare outwardly projecting knobs 59' which hold the bail yieldingly invertical position when at rest.

From this description it will be seen that a very simple structure isproduced which is very effective in operation, providing at very smallcost a toy carpet sweeper that actually works. The brushes revolve bytheir hub bearings -11 very readily in the smooth deressions 51 in thecenter of the support 5. The support 5 retains the parts yieldinglytogether and serves a means for preventing the floor wheels sliding offtheir journals, and insures their very free operation as a consequence,and the ready removal and insertion of the brush.

From what has been described it will be seen that this improvedstructure provides a strengthening plate at the end which serves as thelongitudinal retainer for the floor wheels and as the pivot or journalsupport for the brush. It also provides a reinforce support for the bailwith means for holding it in vertical position when out of use. Thestructure is very strong and lends itself to very rapid and at the sametime nicely finished construction.

\Vhile I have shown the case of paper construction, which is held verysecurely as here shown, the invention is, of course, of widerapplication, and I desire to claim this feature both specifically andbroadly as pointed out.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a carpet sweeper, the combination of a case with slotted ends toremovably receive the brush and enlarged apertures for the movementofthe floor wheel axles, a rotary brush with driven wheels therefor withaxially projecting pivots, dust pans with straight extended stub axlepins fixed in each end thereof and extending through said enlargedapertures in the case ends, floor wheels journalled on said axle pins,and a guard plate at each end with depression for the said brush pivotand with wheel retainer portions to retain the wheels on the said axles,comprising a flat base part attached to the casing, the said retainerparts being offset in spaced parallel relation to the base part.

In a carpet sweeper, the combination of a case with slotted ends toremovably receive the brush, a rotary brush with driven wheels thereforwith axially projecting ivots, dust pans with straight extended stu axleins fixed in the ends thereof and exten ing through the said case ends,floor wheels journalled on said axle pins outside said case ends, and aguard plate at each end with a depression directly engaging the brushpivot and with wheel guard portions for said floor wheels, eachcomprising a flat base part attached to the casing. the said guard partsbeing ofiset in spaced parallel relation to the ends of said sweepercase.

In witness whereof I have hereunto set my hand.
